 ## Why?
 
 When conversations get long, the model runs out of context. Most tools hard-truncate — silently dropping earlier messages. **billion-context** gives the model a `compress` tool: the LLM decides **when** and **what** to compress into high-fidelity summaries, preserving critical details (file paths, decisions, error strings) while reclaiming context space.

 The compression engine is [`acp-kernel`](https://github.com/ranxianglei/acp-kernel) — a platform-agnostic, MIT-licensed library with 208 tests. It's bundled inline into `dist/index.js`, so there are zero runtime dependencies.

 ## 为什么选择 billion-context
 
 当对话变长,模型的上下文会耗尽。多数工具采用硬截断 —— 静默丢弃早期消息。**billion-context** 把 `compress` 工具交给模型:由 LLM 决定**何时**压缩、压缩**什么**,将内容压缩成高保真摘要,在回收上下文空间的同时保留关键细节(文件路径、决策、错误字符串)。
